http://www.usmarshals.gov/history/index.html Even after the creation of more than 50 specialized federal law enforcement agencies during the 20th century, the Marshals retained the broadest jurisdiction and authority. For over 200 years now, U.S. Marshals and their Deputies have served as the instruments of civil authority used by all three branches of government. Marshals have been involved in most of the major historical episodes in America's past.
The Gang Resistance Education and Training Program (G.R.E.A.T.) is a school based, law enforcement officer-instructed classroom curriculum. The G.R.E.A.T. lessons focus on providing life skills to students to help them avoid delinquent behavior, youth violence, and gang membership. The Office of Justice Programs, Bureau of Justice Assistance (BJA), administers the G.R.E.A.T. program. The U.S. Marshals, in collaboration with local law enforcement and community partners, began a nationwide initiative in 2007 to teach the G.R.E.A.T. program.
